Assemble a simple, pre-made circuit with light that you can incorporate into your 3D designs.
3. Trim the LED legs
Notice that one leg of the LED is longer than the other. This is to indicate which pin is positive and which one is negative. The longer pin is positive (+) and will correspond with '+' side of the coin battery used to power the LED.
The
length of the pins as they come are too long to fit into the Glow
assembly. Use the wire cutters to snip off the shorter negative (-) pin
so that it's about 1.5cm long. and the longer positive (+) a bit longer.
